Seamless Alloy Carbon Steel Pipe  

According to different applications, seamless steel pipes include thick-walled seamless steel pipes and thin-walled seamless steel pipes. Seamless steel pipes are widely used. General-purpose seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structural steel or alloy structural steel, depending on the material. For example, seamless pipes made of low carbon steel such as No. 10 and No. 20 are mainly used as pipelines for steam, coal gas, liquefied gas, natural gas, various petroleum products and various other gases or liquids; 45, 40Cr and other medium carbon steels The manufactured seamless pipes are mainly used to manufacture various machine fittings and pipe fittings. Special purpose seamless tubes are used in boilers, geological exploration, bearings, acid resistance, etc. Such as petroleum geological drilling pipes, cracking pipes for petrochemicals, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and…
